W3E32M72S-XBX - 32Mx72 DDR SDRAM

Datasheet Summary

Description

The 256MByte (2Gb) DDR SDRAM is a high-speed CMOS, dynamic random-access, memory using 5 chips containing 536,870,912 bits.

Each chip is internally configured as a quad-bank DRAM.

The 256MB DDR SDRAM uses a double data rate ar chi tec ture to achieve high-speed operation.

Features

Data rate = 200, 250, 266, 333Mbs Package:.
